VELOCIPEDE DRIVE-WHEEL.

SPECIFICATION forming part of Letters Patent N 0. "509,801, datedNovember 28, 1893. Application filed February 11, 1893. Serial No.461,917. (No model.)

To aZZ whom it may concern:

Be it known that 1, PETER GENDRON, a citizen of the United .States,residing at Toledo,

in the county of Lucas and State of Ohio,

have invented certain new and useful Improvements in VelocipedeDrive-Wheels, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention consists in constructing a wheel, upon the crank shaftitself, that is securing the hub flanges which carry the spokes,directly to the crank shaft, dispensing with the usual sleeve or skein.

The invention further consists in the peculiar construction of thejournal, and further in the peculiar construction of the pedal, all asmore fully hereinafter described.

In the drawings, Figure l is a section through the drive wheel of avelocipede, showing the crank shaft and hub in elevation. Fig. 2 is across section through the hub, illustrating the manner of securing thehub flanges to the crank shaft. Fig. 3 is a section on line w a: in Fig.2.

The crank shaft of my wheel comprises the usual central straight portionA, the arm B bent at substantially right angles thereto and the arm 0bent at substantially right angles to the arm B.

D are lugs or keys which are preferably formed by pinching up the metalon opposite sides of the central portion A of the crank shaft a distanceapart equal to the distance at which the hub disks E are to be secured.This I preferably do while the crank is straight. The hub disks E of anysuitable construction are then slipped over the ends of the shaft andforced up upon the inclined faces of the lugs D, as shown in Fig. 2.These disks are provided with a suitable col- .lar F, embracing thecrank shaft to give a proper bearing thereon, and are preferablynotchedto engage the lug or key D. The spokes G and rim H are thensecured to the hub flanges, the ends of the spokes being riveted orupset in the usual manner. The shaft thus far is preferably leftstraight and is now bent into the shape shown in Fig. 1, and rings I aresecured near the ends of the straight portion A, and a suitable distanceaway from the collars F to leave'a journal J between. The crank portion0 of the shaft is provided with a reduced end K with which the flanges Lof the pedals M are adapted to engage. The shaft is provided with thebifurcated or cupped end forming a flange or flanges N which may bepeened over as shown at the left hand in Fig. 1 against the end of thepedals to hold them in position. The

drive wheel is now in position to be engaged with the boxes of the frontfork of the velocipede.

The process of securing the hub flanges in position upon the crank shaftis immaterial as it may be done in various ways both before or after thecrank shaft is formed, the essence of my invention being, as Iunderstand it, the securing of these flanges directly upon the crankshaft itself, so that this shaft with the flanges forms the hub of theWheel.

What I claim as my invention isl. Adrive wheel for velocipedesconsisting of a crank shaft, having integral cranks, hub disks on theshaft, fixed keys integral with the shaft and interposed between thesame and disks and the spokes and rim, substantially as described.

2. A drive wheel for velocipedes composed of a crank shaft, keys fixedintegral with said shaft, hub disks secured upon said keys, and thespokes and rim, substantially as described.

3. A drive wheel for velocipedes composed of a crank shaft, taperingkeys formed integral with the shaft, hub disks forced on the keys, andthe spokes and rim, substantially as described. g

4.. A drive wheel for velocipedes composed of a crank shaft, hub disks Ehaving collars F, keys D 011 the shaft with which the disks are engaged,the spokes and rim, the rings I pressed upon the straight portion of theshaft to form journals J, substantially as described.

5. In a drive wheel forvolocipedes the combination of the crank havingthe reduced end portion K of the pedals M havin the T flanges Lengajging such reduced portion and PETER GEN DRON' 5 the flanges or lugsN on the end of the shaft Witnesses:

turned over against the endof the pedal, subl M. B. ODOGHERTY,

In testimonywhereof I affix my signature in presence of two witnesses.

stantially as described. V N. L. LINDOP.
